To all whomgtmoyconcem:

Beit .known that I, PASQUALE J. Borrero, n. citizen of the UnitedStates, and resident of Mount Vernon, in the county of Westchester andState of New York, have invented certain new and useful Improvements inMultiple Switches, of which the following is a specification.

This invention relates to electric circuit closing devices and has moreespecial reference to nu improved multiple contact switch.

The invention has for its dominant object to provide a switchespeciallyadapted for use in comiection with-three wire sys' tems whereby twocircuits can he closed or opened indepjendently of each other.

Another o ject ofthe invention is to. provide a switch oi the charactermentioned which can be used upon winding and reelin apparatus, theswitch being provided wit i a, lamp socket iii connection with certainof the contacts whereby a lam can he illuminoted and vmoved to thedesired points; the other of the contacts beingconnected to the motorfor rotating or rewinding the reeling applrntus. A

o improvements in the details and arrun ements of parts will be apparentfrom an inspection of the accompanying drawings, in connection with thespecific descripV tion hereinafter contained, wherein the preferredemb'odiinento the invention is disclosed for the pur ose of imparting afull understanding oi t e invention.

In the drawings:

Figure 1 ,is a vertical section through the im roved switch;

ig. 2 is e side elevation of the improved circuit closi means; and

Fi 3 is a isasseiribled' detail in perspective t ereoi. Y

F' 4 is a da rammatic view show' by otted lines vt e device, while by fulines there is shown the elements conned therein, the circuits, lamp andexternal translating device. e

Referr' more vspecifically to the drawings, wherein like referencecharacters desiguate corresponding perts in the several views, theswitch may stated to include en internally screw' threaded socket forreceiving an incandescent .lam as indicated by the letter S. A.sectional insulating base B Vis provided and has the socket S securedthereto, while the usual type of insulatin protecting hood or casing'. Cis arrange Specification of Letters Patent.

ed with a laterally offset apertuied end through which a screw 2 ispassed into enegement with a threaded opening formed in the'hase;obviously, this screw sorvin as the binding post or terminal for one o t.the conductors c. The remaining extremity of the contact l is arrangedupon the opposite side of the base B adjacent the circuit closinfelements 3, one end of which is siight offset and a ertured in orderthat it' can e secured to c bese B in a suitable seat formed therein; a.second binding post oomprisin a piece 0i metal t having one end thereoapertured and offset at 5 and the other end also apertured and securedto the 'base B and engaging the fixed end of the circuit closing element3 at all times. A screw 6 is passed through; the apertured ond of thebinding post i into engagement with the insulated hase B to serve as aterininal with which another of the conductors o are engaged.

To facihtatc operation of the movable circuit closing element 3 aninsulated button 7 having a screw threaded shank is turned intoengagement with the free end thereof, and, as shown in Fig. 1, passesthrough n, suitable opening formed in the casing C of the switch. By soconnectin the several conductors c it will be appreciated that bydepressing the button 'i' an causing the coutact element 3 to engage thecontact element l a circuit may be closed therethrough.

sthe secondary switch, the ordinary key typeV oeircuit closer isemployed and comrises the usual shaft 8 which is journaled intheinsulated-hase B and carries upon one end thereof a cam 9, which camis arranged adjacent si. substantially U-shn d contact member 10 and isadapted to e engaged therewith upon rotation of the shaft 8 by means ofthe ner piece 11 mounted thereon. A U-shape( metal piece or strip 12 isarranged upon the base B and has its opposite ends provided withopenings for receiving the ends of the shaft 8 therethrough. Upon thisstri 12 a leaf spring 13 is mounted and norma has bearing upon the cam9. The remaining of the conductors c extends into engagement with thestrip 12 and, obviously, serves as means for supplying the currentthereto in order that a circuit may be closedthrou h the same and throuvh the conductor whic is secured to the Ilshc ed contact element 1 uponVthe enga ing diie cam with the contact element l it of course beingunderstood that a lamp or other power receivin element is arranged inthe socket s. ig. 4: of the drawings the electric bulb L has its circuitcontrolled by the switch 9, while the external translatin device M iscontrolled by the switch 4.

ith my improved multiple contact switch, it will be appreciated byworkers in this art that I am enabled to successfully use the sameuponvarious forms of electric translating devices, the switch heiligespecially adapted for receiving and illuminating the ordinaryincandescent lamp L, the conductors c beingMsccured to an electrictranslating device By closing the key operated switch 41 the lamp L maybe illuminated and by de ressing the button 7 a second circuit may dieclosed independently ofth lam circuit, this circuit lsreierably incluing t etranslating device Thus, when the lamp has 'been moved to thedesired point and it vis then desired to energize the translatingdevice,the circuit controlled by the contact element 3 is closed, therebyenergizing the electric translating device.

While I have herein illustrated und described with a considerable degreeof purthe several parts which may be modified within awide range Withoutdeparting from the essence of the invention, the construction shown andthe description based thereon being intended to be taken in an illustrative rather than a limiting sense.

I claim In combination with an incandescent lamp shell, a multi )lepoint switch including an insulatingr ase, a substantially U- shapedcircuit terminal secured to said base and connected to one side of anelectrical circuit, a second circuit terminal on the base connected tothe opposite side ci said circuit, switch means copcrating with saidsecond circuit terminal for closing un electrical circuit through a lampengaged in the shell and with tlie first und second nientionedterminals, a resilient contact arm cured to the insulatingr base adaptedto cngage with one end of said U-shaped circuit terminal und connectedto one side of u. sccond and exterior electrical circuit, said U- shapedcircuit terminal serving,` :1s a common side for said first and scccndmentioned electrical circuits1 and a finger button connected to the freeend of the Contact and arranged exteriorly of the shell.

In testimony whereof I affix my signature hereto.
